During the experiment, three process factors—Layer height, extrusion temperature, and printing speed—are considered, and their associated response parameters, ultimate tensile strength, and surface roughness are established. Themultiple-criteria decision-making strategy, which incorporateshybridGRA-TOPSISandANOVA, is employed since therearetworesponsesandtwoobjectives.Theidealparametersdetermined by these statisticalmethodswereanextrusion temperatureof2600c, layer heightof0.2mm,andprintingspeedof60mm/s.Thisstudyconcludesthat theoptimalparametersfor theinvestigatedexperimentaldataareconvergent regardlessofthetwotechniquesused.nd |
